                        <p class="text-gray-700 mt-2">注册中心是Dubbo架构中的核心组件，负责服务注册与发现，直接影响服务调用。而监控中心是可选的辅助组件，仅用于采集和分析数据，不影响核心业务流程。</p>

                        <p class="text-gray-700 mt-2">虽然监控中心故障不影响业务，但缺少监控会使系统运维变得盲目，无法及时发现潜在问题。建议实现监控系统的高可用，并设置本地数据缓冲机制。</p>

                        <p class="text-gray-700 mt-2">对于关键业务系统，建议部署监控中心集群，并配置数据持久化。可以采用Prometheus+Grafana等替代方案增强监控能力。</p>
